CENTRIFUGAL LIQUID-SEPARATOR.

SPECIFICATION forming part of Letters, Patent No. 734,585, dated July 28, 1903. Application filed September 12, 1902. SeriaI NO. 123,068- iNo model.)

To all whom it may concern.-

Be it known that I, J ULES Mnnorrrn, a subject of the King of Belgium, residing at Remicourt, Belgium, have invented certain new and useful Improvements in Centrifugal Separators for Liquids; and I do' hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

As is well known, the arrangement within the drums of centrifugal separators-such as centrifugal milk-separators, for example-Of inclined Walls or partitions dividing the liquid to be separated into sheets and cutting the radius of the drum facilitates the separation of the constituent parts of different densities. The partitions which are employed to this end are either concentric or eccentric to the axis of rotation of the drum. In the case of concentric partitions the latter may be of various'forms, such as conical, zigzag, undulating, die. They are superposed within the drum and are situated in a vertical plane or a horizontal plane, accordingly as the drum may be rotated in one or the other of such planes. In cases in which the partitions are eccentric they are arranged at right partitions may prod uce a sufficient marked effect upon the separation that they shall be sufiicient innumb'er, and all forms of such apparatus as hitherto constructed require the expenditure of much time for dismounting, cleaning, and reassembling. In order to facilitate the dismounting, it is only necessary to connect the parts at the axis; but this arrangement does not permit of the employment of a large number of blades, because cleaning them would be rendered difficult if not impossible. The arrangement which forms the subject of this invention serves to obviate these defects. V

In the accompanying drawings, Figure 1 is a vertical section of one form of the improved separator. Fig. Zisaplan of the same. Fig. 3 is a sectional elevation of one series of blades on the line G H of Fig. 4.. Fig. 4 is a plan of the same. Fig. 5 shows. the drum mounted within a casing and illustrates the manner of using the same.

In carrying out the invention I insert within the usual drum aset of connected blades A, Figs. 3 and 4, the number of the blades in a set being sufficiently small to present no obstacle to cleaning; but instead of connecting the blades or partitions composing this set one with the other throughout their en-' tire heightlonly connectthem for a portion of such height, as at D, Fig. 3, so that the remaining portion E (about three-quarters of the whole height) may be free, leaving a greater or less interval or space between the axis F and the free inner edges of these blades, which gives the form shown in Figs. 3 and 4. In other words, the partitions in the set are Well separated,except at or near their lower extremities, so as to form a central vertical recess or clearance E in the set. I then arrange in the same manner a second series, as at B, Fig. 1, only instead of the point of connection D being as in the first part I arrange it at another point in the height-as at D, Fig. 1, for example. part may be arranged in a drum within which the first part has already been mounted, the blades of each of these two parts being interposed between each other, while the points of connect-ion are superposed. In other words, the partition-connecting members D in this set occupy a position within the recess E of the first -'rnentioned set. Said connecting members D are, however, of no greater height or width than is desirable for effecting a suit-- able connection, so that theupper portion of the recess E still remains unoccupied,althougl1 eight partitions are assembled. In this man- Obviously this second in one set shall not coincide as to height with the connections in any other set. In Figs. 1 and 2 I have shown three of these sets of blades. Instead of soldering the blades in each set directly one to the other they may be connected in any other suitable manner, as by the intermediary of connecting parts, such as hubs, star-shaped pieces,and the like.

It will be understood that owing to the infectious nature of a single drop of impure milk it is essential to give the separator frequent and thorough cleansing. It has heretofore been considered an objection to the use of numerous vanes or partitions'within the drum, that they are difficult of access for the purpose of cleaning, and besides they present numerous crannies and other openings in which drops of impure milk are likely to become secreted, so that they are difficult to cleanse. My invention, it will be seen, enables the use of any number of partitions and avoids this objection, since the entire group of partitions may be divided into as many units as desired, each unit consisting of two or more well separated partitions, which may be assembled or nested with the remaining units and subsequently may be lifted out one at a time and cleansed with great facility, every part of each unit being easily accessible and the drum itself being also left open and free of access.

It will be seen that the unit illustrated at Fig. 4 consists of a set of partitions fastened together at their inner edges and that this unit is adapted to nest with other units, as B and 0, Figs. 1 and 2, the partitions in one unit alternating with those in another unit and the connections, as D and D, being diversified to permit the nesting of the units. The partitions preferably converge and may be of various forms within the scope of my invention. Preferably the partitions are rigidly connected, the connections being either integral or otherwise. It will be understood that the partitions in one unit may be {connected at their lower ends and those in another unit at their upper ends, while those in still other units may be connected at their middle portions, and all maybe nested in a drum, as seen in Figs. 1 and 2. The partitions in each unit are preferably discrete, being separated for the accommodation of the connecting members of other units.

At Fig. 5 it will be noted that the drum B may be formed of lower and upper sections 1) and Z), fitted together and held by means of a threaded hoop A, and it will be understood that the usual packing (not shown) may be inserted between the edges of the drum-sections. The drum is suspended by means of a hook Z upon a vertical revoluble shaft D, which latter may receive its rotary movement from a belt or in any other usual manner. The drum is suspended upon the hook Z by means of an eye Z, whereby the drum is caused to rotate, but is permitted to swing slightly. Said eye Z is formed with a shank Z which is secured to an inverted yoke Z the ends of which are secured at Z within and to the roof of the drum. Milk is fed into the drum through a spout T and is received by a bowl G, which is supported by a central thumb-nut G upon a threaded stud G dependent from the shank Z the rim of the bowl preferably contacting with the roof of the drum. The milk flows from the spoutT into the bowl G, which becomes filled, and is distributed therefrom through openings 0 into the drum B, as indicated by the arrows. The partitions A, B, and O facilitate the separation of the constituents of the milk into two bottles, according to the order of their specific gravities. The separated milk being the heavier collects at the concave part of each partition, while the cream collects at the convex part thereof, and on account of the diiferences in the specific gravities the cream forms an inner body at the axis of the drum, while the separated milk passes to the outer Wall of the drum. The cream passes down through a central outlet T, depending from the floor of the drum, and falls into a basin T from which it flows out through a spout M. The separated milk, which flows to the side walls of the drum, escapes down past the edge of a false floor F, provided in the drum, and passes beneath the same through an outlet P at the bottom of the drum and escapes therefrom into a basin E formed in a casing E, in which the drum is placed, from whence it escapes through a spout N, all as indicated by the arrows.
